Are you still wondering how to choose a water purifier?

First, depending on qualifications.
Consumers can visit the Public Network of Health Administrative License when they purchase. The relevant data of a water purifier are all verified and recorded on the website. If you are not sure about that criterion, you can go online to find the data and compare them.

2. Look at the material.
At present, there are stainless steel, fiberglass reinforced plastics, cast iron, aluminium, food-grade resin or PVC and other materials on the market. The first three materials are of good compression resistance and can be used as pre-filter (central machine). The latter two materials belong to the poor compression resistance, which can only be used in the back end of the front filter (central machine) for direct drinking machine. Stainless steel is the best and the price is relatively high.

Third, definite function.
Choosing a water processor should first clarify its purpose. First of all, from a large concept, it is necessary to purify or soften the water. Purified water is the removal of sediment, impurities, bacteria, heavy metals, residual chlorine, organic matter and some minerals. Softening water is the calcium and magnesium ions in the dewatering water, the most direct is scale.

Fourth, filter material selection.
At present, PP cotton, activated carbon, KDF, ultrafiltration membrane, RO membrane (reverse osmosis suitable membrane, reverse osmosis induced membrane), quartz sand, maifanshi, infrared mineralization ball and so on are commonly used in water purification materials. Different water purification materials will produce different purification effects, consumers can choose a suitable water purifier according to their desired purification effect.

Fifth, the ratio of size.
This is the most realistic way. Water purifiers are usually determined according to the instantaneous water output. They can be called central water purifiers when they exceed 20 tons/hour and direct drinking water purifiers when they are less than 10 tons/hour. This water output is related to the volume and diameter of the inlet and outlet, usually the larger the instantaneous water output of the water purifier. More popular, that is, the comparison of effluent volume, the effluent volume of large water in the above efficiency of water purification must be higher.

Sixth, service.
First is the pre-sale service of installing water purifier. According to different water quality, different waterway design, different room size and other factors, we should give more perfect purchase suggestions and inquire about the use effect after installation, and then improve it according to customer's requirements. In addition, the leakage of water treatment materials due to various reasons S may occur in the course of use, so it is necessary for the water purifier to be insured by the insurance company. As the saying goes, "If you are not afraid of 10,000, you are afraid of 10,000", when an accident occurs, the insurance company will pay compensation according to the loss of customers.

These are some precautions when selecting water purifiers. I believe that after reading this article, you will have a new understanding of the selection of products in this area. Buying such products is to do more homework, after all, for the whole family to buy products.
